1'0 all whom 'it 'may concern:

Be it known that l, fumant luowN IVILsoN, a subject ot' the King ot England, andA a resident of No. Al-'t DicksoiLRoad, IVellHall, S. E, 9, in the county of Kent. Kingdom of Great Britain, have invented certain new and useful Improvements in Mechanism for Operating Single Sleeve Valves, of which the following is a specification, reference being had to the accompanyino drawings.

sl'he present invention, relates to mechanism for operating single sleeve valves of internal combustion engines, steam engines and thelike, a principal object of the invention being to provide for this purpose a. simple form of mechanism which is positive in action and effective to oscillat the gleeve valve in one direction during the induction or inlet stroke of the piston, to then return the valve to and permit it to remain in normal position, that is, the position in -whieh the inlet and exhaust ports ot' the engine are closed,l during the compression power strokes of the piston, to then oscillate the valve in the opposite direction during the exhaust stroke of the piston and finally return it to normal position, thus completing one cycle of operation.

A further object of the invention is to provide a valve operating mechanism of the character aforesaid whlch is capable of adjustment to vary the time of opening and closing of the inlet and exhaust ports in` conformity' with the speed of the engine or for other purposes as may be desire Further objects, advantages and novel features of design, construction and arrangement comprehended by the invention will be apparentas the nature thereof is vbetter understood from the following description of one embodiment of the invention which I have illustrated on the accompanying drawings forming a part hereof.

While the invention is adapted for employment in various forms of sleeve valve engines, it particularly lends itself to use Y in connection with a sleeve valve ot' the type disclosed and claimed in and which forms the subject of an application for Letters Patent of the United- States executed by me of even date herewith and entitled Improvements in single sleeve valves for internal combustion engines, steam .engines and the like and in the said drawings I have therefore shown' and will new proceed to 'describe a form of the invention embodied in an internal combustion engine of the character shown in said application.

In the accompanying drawings Fig. 1 is a fragmentary vertical central section through the cylinder of an engine of the character aforesaid and embodying valve actuating mechanism constructed in accorciance with the present invention, certain of the parts being shown in elevation andiFig. 2 is a top plan View thereof. Fig. 3 is an enlarged fragmentary elevation of a por tion of the cam shaft and adjacent parts and 4 is an end view thereof. Fig.` 5 is a fragmentary bottom plan view on a reduced scale of the parts shown in Fig. 4; in normal position and Figs. (i and 7 are similar views showing the positions of the cam rollersat the respective extremities of their oscillatory movement. Like numerals are used to designate the same parts in the several figures.

As shown, and as more fully disclosed in my said application, the engine embodies the usual cylinder block l disposed on a crank case 2 which enclosesthe crank shaft 3 connected by the connecting rod 4 with a piston 5 inthe usual manner, the cylinder block being arranged toI provide a space or chamber 6 for the circulation of cooling Water and the interior ot' the block being bored out to for1n-the cylinder T in which is disposed a sleeve valve 8 having an inwardly curved head terminating'in a spindle 10 extending through the cylinder head 1l, provided with an internal chamber 12 for the circulation of coolingrwater, the sleeve valve Sbeing rotatable within the cylinder and provided in its head with ports 13 adapted vto register with ports 16 andl 17 formed in the cylinder head.

Through these latter ports, when the ports in the sleeve are properly aligned therewith, the fresh gases can be drawn into the interior of the sleeve which forms the combustion chamber of the engine on the inlet stroke of t-he piston and exhausted from the interior of the sleeve on the exhaust stroke of the piston. As these several parts are more fully disclosed .in said application reference thereto may behad for a more extended description thereof and of their method of operation if required.

In the operation of an engine of the aforoi said character it is requisite that oscillation of the. sleeve 8 be effected in opposite direc-- (lll reagent to n'iowen. -1 f hiring the erts 13 @ferent ports `in the head. to permit the n'iixlnre to he diie "n into the cylinder o? ine .piston and the to oe disohoreod that the sleeve he ineindnring; the roniprrssion of 'the piston suoli that porto in 1, :e sleeve are ont of registry nil ol? the poils inthehend, and for these results; lf inoyY in neomdorn'e lent i lion, prei 'de nierfhn- 'no following; Charm-te -tor notoire leere the crunk onse and extending erzinlrshzii'ft l provide n ofnn fdsnpiortnd in snitolle hearings and iven :tro the ornnlt shalt in itiny oonnient wey by gearing, Silent eli-iin or. o hire and preferably et oneihnlt the speed eronir elio-ift. llhe Corn shaft is pro L if v h eylinder o the engine with e udinnliy spaced come 2l., 22 nre respectively operative to ortnzite oil/ore 9,3 and. 24; tho" faces' of which n'niy liv eronnte it de. :red instead of lint, 's inonnt i, for rotation upon te ends of o @in 25 which in turn. the .lower enti oi" un oiliset lngY 2G the lower endy of a spindle or wiel to it e i 'the rollers being held on the end oil -le 'pin in any suitable Way es, for omni-- lilo, by or keys 28 driven through the The sigindle 27 is y'rotatably mounted in 'nl-onli. und supported in eiiitehle and preferably in such manner os t any material longitudinal play, i end of the spindle terniinnling :it convenient distance above the cylinder if, The Several parte inst described so ""l int the goripheries ot the rollers e igentto a vertical l tound. penning thrifni-gh the i l'. i ond the ripper e nfl yoli tnlsly Conneeled with the he spindle l() oi l sleeve "iin eonnorti-on nioy helm-ined "wanner il', n'r'y he eonven. l i .e'il n.y profi" ng the ripper.
